Trying to Post

I have been trying to post all morning and I keep getting that page that tells me to refresh my page because the site where I am trying to go is not available.  When I typed my one sentence "test" message, it did fine.  The post I am trying to send is longer but I cannot get it to post.  Any suggestions?

Hey. Thanks for getting back to me. I was finally able to post - I had to shut my computer down and start all over. I was beginning to think that it was because my post was too long. I started a new post - had a question that I thought others here might be able to answer.

Thanks again and have a great day!
